A Software-Defined Network Configuration Providing Differentiated QoS to an eHealth Environment

This paper presents an approach to Quality of Service (QoS) management aimed at providing services aware of the urgency in the sepsis diagnosis. The model proposes a non-concurrent environment for services delivery where the sepsis application will guarantee QoS using Software Defined Network (SDN) resources. The implementation of the proposed model shows to be feasible and functional and will avoid concurrent data in the delivering of services with the sepsis application.

An Autonomic QoS management architecture for Software-Defined Networking Environments

Software-Defined Networking (SDN) is an innovative approach to provisioning and delivering QoS (Quality of Service) services, yet it is still devoid of context-differentiating services. In this paper we propose a network application (Autonomic QoS Broker) and a controller module that implements the OpenVSwitch Database Management Protocol (OVSDB). These two components were implemented and validated in order to provide QoS management with queue prioritization in a SDN environm.. [limit of words]

An Autonomic QoE-Aware Management Architecture for Software-Defined Networking

Context-oriented computing has introduced new challenges in Quality of Service (QoS) management since the diversity of applications, forms of access and the TCP/IP architecture model make it difficult to provide services aware of Quality of Experience (QoE). In view of that, we propose an autonomous architecture of service provision and delivery that is QoE aware. The proposed components were designed and validated in a Software-Defined Networking environment.. [limit of words]

Provisioning and Delivering Sepsis Data Supported by an Enhanced SDN Environment

Medical applications, along with Information and Communication Technology (ICT), have contributed with many solutions to support the treatment of SEPSIS. However, there are few solutions for the transport of sepsis data with Quality of Service (QoS). In this paper we propose a self-manageable architecture for the provision and delivery of sepsis data using Software-Defined Networking (SDN). To evaluate our proposal, we conducted our experiments in the laboratory... [limit of words]
